Application filed April 12, 1918. Serial No. 228,129.

To all whom it may concern Be it known that I, JoHNJ. Donovan, a citizenof the United States, residing at Boston, in the county of Suffolk andState of Massachusetts, have invented new and useful Improvements inDrinking- Fountains, of which the following is a spec1fica tion.

This invention has for its object to provide a drinking fountain for usein schools, industrial establishments and other public places, and moreespecially to provide a fountain which is sanitary and unlikely tospread disease.

As a result of prolonged investigation and study, it has been determinedby bacteriological examination of certain fountains now in use that,where the water jet is directed vertically, it frequently happens thatthe water carries with it the germs which have been deposited upon thefountain with the saliva of the previous user. This occurs especially inthe cases referred to, because the user places his lips upon someportion of the fountain, notwithstanding the height of the 'et. 3 Toovercomethis danger to thepublic, I have produced a fountain in whichthe jet of water is directed upwardly and laterally to insure that itshall not return again upon the nozzle. Then, to prevent the user fromplacing his lips too closely to the nozzle, I form the latter with adomewhich protects the nozzle, and which is itself continuously washed bywater separate from that issuing from the nozzle. These and otherfeatures which mark my improved fountain are explained more at length inthe following specification and are particularized in the claims.

On the drawing,- Figure 1 represents in front elevation a fountainembodying my invention.

Fig. 2 represents a plan view of the same. Fig. 3 represents an invertedplan view, to show the valve which controls the supply of water to theseveral ports or orifices,

Fig. 4 represents a section on the line 4-4 of Fig. 1. a

Fig. 5 represents a similar section, and in addition shows the valve andthe top screw in section.

Fig. 6 represents a cross section on the hue 6-6 of Fig. 4. i

Figs. -7 and 8 represent respectively the top screw and the valve.

Referring to said drawings,the fountain there shown consists of adome-shaped head which may be screwed upon the end of a pipe 10. Thedome 11 is hollow, except as hereinafter described, and is cast upon abase 12 which is interiorly threaded to receive the pipe 10. Across thebottom of the dome at its juncture with the base, there is a transverseweb or partition 13, and across the dome there is a second web orpartition 14, between which a water chamber 15 is thereby formed. Thischamber communicates with the interior of the base through a valve screw16 having a longitudinal aperture 17 and transverse ports 18 close tothe head 19 of the screw. By adjusting the valve 16 in. relation to theweb 13, the ports 18 may be partially or entirely opened or closed.

Extending from the web 14 to the top of is swelled forwardly as at 21.The pillar swells outwardly at its upper end and merges in the side wallof the dome to provide an increased thickness of stock under the top andthe middle of the dome. A duct or jet aperture 22 is formed in theforwardly swelled base of the pillar which thereby constitutes the jetnozzle, and this duct is inclined so that the jet is directed upwardlyand forwardly at an acute angle to the ver tical, the top of the jetbeing in front of the fountain. The dome has in its front an elongatedvertical slot or opening 23, which starts at the partition 14 andterminates below the top of the dome to leave a shelf or overhang 24which is directly above and covers the end of the aperture 22, asclearly shown in Figs. 2 and 4.

Through the pillar 20, a duct 25 extends from the water chamber 15 to acentral cylindrical recess or cavity 26 in the top of the dome to permita stream of water, in dependent of that issuing from the main nozzle, toflow for continuously washing the exterior surface of the dome. Areducing valve, in the form of a screw 27 is screwed into the upper endof the duct 25, and it has a beveled head 127 which nearly fills therecess and leaves a narrow annular passage between its edge and theencircling wall of the recess. The lower end of the screw has a reducedcentral opening 28 communicating with lateral ports 29 for deliveringwater from the central duct to the bottom of the recess 26. Thus a smallstream of water the dome, there is a core or pillar 20 which to causethe head to be submerged in the pool of water therein.

The fountain is provided with an antis uirt feature so that amischievous 3erson cannot, by placing his finger on the nozzle,spray thewater laterally. It will be ob served that a port 30 leads laterallyfrom the nozzle to the interior of the dome. When the jet of waterissues normally from the nozzle, substantially none escapes from theport, but, if the jet 'aperture'be closed, the water will issue into theinterior of the dome. The'top surface of the partition 14; slopesdownwardly and forwardly toward the opening ..3. The interior of thedome and the surface of the partition 14 may be constantly flushed withwater by providing ports 31 through the top of the dome and spaced aboutthe recess or cavity 26. These ports also prevent a person imbibingwater from the top as air would be drawn into the mouth and prevent freesuction.

By reason of the construction which I have thus illustrated anddescribed, a person cannot place his lips 011 the nozzle since it isiinpossible'of access, and there is no chance of saliva being depositedthereon.

The top of the jet being laterally remote from the fountain, there is nooccasion for resting any portion of the face on any part of the latter,and, since the dome is constantly flushed with Water, not only is itkept cleaner, but the fact that the face will be wetted incase it comesin contact with the dome, acts as a deterrent to touching the dome. Thenozzle is located well above the partition 14:, so that there is nodanger of any water flowing along the surface of the latter beingcarriedupward by the jet. The

whole fountain-is constantly washed by an ever-flowing stream, which isindependent of the drinking-jet. It is intended, of course, that thedrinkingjet shallpass through the opening 23 in the dome withoutimpingement on the walls thereof.

The regulating valve, which controls both the jet and the washingstream, is located within the fountain, and cannot be tampered with solong as the fountain is in place since at such time it is inaccessible.

Having thus explained the nature of my said invention and described away of making and using the same, although without attempting to setforth all of the forms in which it may be made or all of the modes ofits use, What I claim is:
